A man arrested for allegedly planning to build a Molotov cocktail to use during the NATO Summit isn't connected to the three terrorism suspects charged Saturday, the Cook County State's Attorney said. Neither was a man accused of soliciting materials to build a pipe bomb, she said.

"While the cases that were charged in court today arose from related investigations, the two defendants are not charged with any involvement in the terrorist case from yesterday, and today’s cases are separate matters," State's Attorney Anita Alvarez said Sunday in a statement. "The two defendants ... each face their own charges arising from separate incidents."

Sebastian Senakiewicz, 24, was charged with a felony count of knowingly making a false terrorist threat. Bond was set Sunday at $750,000. He is due to appear in Cook County Circuit Court Wednesday.

Senakiewicz was arrested by 16th District police officers Thursday afternoon after they raided the home in which he was staying in the 3600 block of North Odell Avenue.

A search warrant issued earlier in the day indicated that police were not only seeking incendiary devices, but also "any and all objects which could be used as a disguise or a container for an explosive or incendiary device."

Mark Neiweem, 28, was charged with a felony count of solicitation for possession of explosives and incendiary devices. Bond was set at $500,000, and Neiweem also is scheduled to appear in court on Wednesday.

Neiweem allegedly met associates in a forest preserve to solicit a PVC pipe, two PVC caps, PVS glue and several model rocket engines to construct a pipe bomb from Hobby Lobby.
